The signaling protocol for B-ISDN should support variety of services including point-to-pont single-connection call, point-to-point multi-connection call and point-to-multipoint connection call. an efficient signaling protocol for point-to-point multi-connection call based on ITU-T Recommendation Q.298X is presented in this paper. Sequential establishment of madatory and optional connections and common routing scheme for synchronization, along with separation of information elements for establishement of multi-connection call are included in the proposed signaling protocol. Limited network resources can be used more efficiently by proposed sequential establishement of mandartory and optional connection for point-to-point multi-connection call which can provide multimedia services. And common routing can be provided effectively by proposed common routing scheme for connectios requiring synchronization like as video-phone and video-conference.
